Many athletes are treated with hot and cold modalities prior to therapeutic exercise, but the effects of these treatments on sensory perception are not clear. The purpose of this study was to examine the effects of hot and cold treatments on sensory perception. We recruited 21 volunteer subjects, who reported for testing on three separate occasions. One of three treatments was applied to the left ankle and foot each day for 20 minutes: cold immersion, hot immersion, or quiet sitting (control). Three variables were measured following treatment: topagnosis, two-point discrimination, and one-legged balance. We assigned treatments and the testing order according to a Greco Latin square. Data were analyzed using a multivariate analysis of variance (MANOVA). No significant differences were detected for the three dependent measures, suggesting that therapeutic applications of heat and cold do not affect sensory perception. These findings indicate that heat and cold applications can be used prior to therapeutic exercise programs without interfering with normal sensory perception as do other analgesic and anesthetic agents. For example, the hypalgesic effect of cold, which is essential to cryokinetics, can be realized without fear of altered sensory perception.
许多运动员在进行治疗性运动之前都会接受冷热治疗，但这些治疗对感觉感知的影响尚不清楚。本研究旨在探讨冷热治疗对感觉感知的影响。我们招募了 21 名志愿者，他们在三个不同的时间点进行了测试。每天将三种治疗方法之一应用于左踝和足部 20 分钟：冷浸、热浸或安静坐姿（对照）。治疗后测量三个变量：位置觉、两点辨别觉和单腿平衡。我们根据希腊拉丁方分配了治疗方法和测试顺序。使用多元方差分析（MANOVA）对数据进行了分析。三个依赖变量均未检测到显著差异，表明热和冷的治疗应用不会影响感觉感知。这些发现表明，在进行治疗性运动计划之前，可以使用热和冷的应用，而不会像其他镇痛和麻醉剂那样干扰正常的感觉感知。例如，冷的镇痛作用对于冷冻运动至关重要，而不会担心感觉感知的改变。
